moonbit_checksum_updater

^{Native MoonBit checksum management with GitHub API integration}

 

 

A native MoonBit implementation of checksum management for WebAssembly toolchains. Fetches releases from GitHub, computes SHA256 checksums, validates integrity, and maintains a comprehensive JSON registry.

Note

Part of the PulseEngine toolchain. Supports hermetic builds in rules_moonbit.

Features

• Native MoonBit implementation of checksum management
• GitHub API integration for fetching latest releases
• SHA256 computation with native MoonBit crypto
• Async/Await support with parallel processing
• Validation system with strict modes and auto-fix capabilities
• Multiple output formats (text, JSON, markdown)

Quick Start

# Update all tool checksums
checksum_updater update --all

# Update specific tools
checksum_updater update --tools wasm-tools,wit-bindgen

# Validate checksums
checksum_updater validate --all

# Validate with auto-fix
checksum_updater validate --all --fix

# List available tools
checksum_updater list --detailed
